Question

the area of square and rectangle are equal if the side of square is 100cm and breath of rectangle 80cm find the perimeter of rectangular

Answer 1

S ×s = l×b
100×100= l×80
10000=l×80
L= 10000÷80
L=125
Perimeter = 2(l+b)
=2(125+80)
=2×205
=410

Answer 2

perimeter of square=4×side=400m
area square=s×s=10000m^2
area rectangle=l×b=10000m^2
b=10000/80=125m

perimetr rectangle=2(l+b)
=2×(125+80)
=410m
