Answers & Solutions:<\/strong><\/span><\/p>\n

1)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

We know that, diagonal = 1.414* side
\nHere, diagoal = 14.14, side = 10 m
\nHeight = Perimeter of square = 10*4 = 40m
\nNow, base = side of square with 784 $m^2$ area.
\nbase = 28
\nArea of triangle = .5*28*40 = 560 $m^2$<\/p>\n

Option B is correct option.<\/p>\n

2)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Circumference of th wheel = pi * Diameter = (22\/7) * 49 = 154
\nNumber of revolutions of the wheel = 3200\/154 = 20.77~21
\nThe wheel will make around 21 revolutions.
\n3)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Ciircumference = 2*(22\/7)*r = 220
\nHence, r = 35
\nNow, area of circle = (22\/7)*35*35 = 3850
\nArea of rectangle is same as that of circle
\nArea of rectangle = 3850
\nLength * breadth = 3850
\nlength = 3850\/50 = 77m
\nTherefore, option C is correct answer.<\/p>\n

4)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Perimeter of rectangle = 4(44) = 176 cm
\nNow, 2*(length+breadth) = 176
\n2*(51+breadth) = 176
\n51 + breadth = 88
\nbreadth = 88-51 = 37
\nDifference between side of square and breadth of rectangle = 37 – 11 = 26 cm
\nTherefore, the correct option is option C.<\/p>\n

5)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

We know that,
\nDiagonal = side * 1.414
\nTherefore, side = 28\/1.414 = 19.8
\nArea of square = 19.8 *19.8 = 392.04 ~ 392
\nTherefore, the correct option is option D.
\n6)\u00a0Answer\u00a0(E)<\/strong><\/p>\n

As we know that circumference of \u00a0a circle will be = $2 \\pi r = 2 \\times \\frac{22}{7} \\times r $ (Where r is the radius of the circle)<\/p>\n

Now parameter is given as 748 m.<\/p>\n

Hence, its radius will be = $ 748 \\times 7 \\div 44 $ = 119<\/p>\n

7)\u00a0Answer\u00a0(A)<\/strong><\/p>\n

As we know that the area of a rectangle is $ l \\times b $ (Where l is length of rectangle and b is breadth of rectangle)<\/p>\n

Which is 1248 square meter with breadth(b) 32 meters<\/p>\n

So length will be = $\\frac{1248}{32} = 39$<\/p>\n

Hence, parameter will be equal to = 2(39+32) = 142 m<\/p>\n

8)\u00a0Answer\u00a0(D)<\/strong><\/p>\n

Let the length be x and breadth be y.
\nx – y = 7
\nThe perimeter of rectangle is 138
\n2x + 2y = 138
\nx + y = 69<\/p>\n

2x = 76
\nx = 38
\ny = 31<\/p>\n

Area of rectangle = 31*38 = 1178
\nOption D is correct.<\/p>\n

9)\u00a0Answer\u00a0(B)<\/strong><\/p>\n

Area of circle = (22\/7)*r*r
\nr^2 = (7\/22)*2464
\nr^2 = 784
\nr=28
\nCircumference = 2*(22\/7)*28\u00a0 =176 metre
\nOption B is correct.
\n10)\u00a0Answer\u00a0(C)<\/strong><\/p>\n

Area of the circle =$\\pi d^2\/4$ = 616
\nd = 28
\nThe length of the rectangle is equal to diameter which is 28 and breadth is equal to radius which is 114
\nArea = 28*14 = 392<\/p>\n\n
