Question

area of a square field is 99856 square rectangular field whose length is thrice its breadth and its perimeter is equal to the perimeter of square find the area of rectangle​

Answer 1

Answer:

11832936 square unit

Step-by-step explanation:

let , breadth = x unit

so, length = 3x

perimeter of rectangle = 2*[3x +x] =8x

perimeter of a square having side a = 4a and area = 99856 (given)

so, a= (99856)^1/2 = 316 unit

so,perimeter of square = 4*a = 4*316 = 1264 square unit

now, as per question,

8x =  1264

x = 1264/8

so, x=158 unit

so, area of rectangle = length * breadth

= 3*x *x

= (3*158)*158 sq.unit

= 11832936 square unit
