Question

A rectangle has an area equal to that of square of side 8.7 m .If the breadth of the rectangle is even.find it's length.also peremeter of both. PLEASE HELP FRIENDS..

Answer 1

perimeter of the square=4a
perimeter=4×a
perimeter=4×8.7m
perimeter=34.8m

perimeter of the square=perimeter of rectangle=34.8m

perimeter of a rectangle=2(l+b)
34.8m=2(l+0.25)
34.8=2l+0.50
2l=34.8-0.50
2l=34 .3
l=34.3/2
l=17.15m

I think it is the answer but I'm not sure

Answer 2

perimeter of the square=4a
=4×a
4×8.7m
=34.8m

perimeter of the square=perimeter of rectangle=34.8m

perimeter of a rectangle=2(l+b)
34.8m=2(l+0.25)
34.8=2l+0.50
2l=34.8-0.50
2l=34 .3
l=34.3/2
l=17.15m
