Question

The area of a square field is 5184 metre square and rectangle field whose length is twice in breadth has its perimeter equal to the perimeter of a square field find the area of a rectangle field

Answer 1

Answer:

Step-by-step explanation:

let one side of the square = a meter

a²=5184

a=√5184

a=2^6×3^4

a=2³×3² = 72 meter

now perimeter of the square=4a=4×72= 288 meter

288= perimeter of the rectangle

let the length of the rectangle is L meter and width is B meter

2(L+B)=288

L+B=144

L=2B    given

2B+B=144

3B=144

B=48

L=2×48=96

hence length of rectangle is 96 meter and width is 48 meter.
