Question

Find the length of a factangle whose breadth 12.5 cm
and perimeter is 80 cm​

Answer 1

Step-by-step explanation:

primeter of rectangle=2(L+B)

2(L+B) 80=2(L+12.5)

2(L+B) 80=2(L+12.5) 80=2L+ 25

2(L+B) 80=2(L+12.5) 80=2L+ 25 80-25=2L

2(L+B) 80=2(L+12.5) 80=2L+ 25 80-25=2L 55/2= L

27.5 = L

Answer 2

Answer:

Length l of Rectangle =12.5m

Breadth b of Rectangle =8dm=0.8m

Area of rectangle = length×breadth

= l×b

=12.5×0.8

= 10m
