Question

the areaof the rectangle is 80 sqcm . if its length is 10 com . what is its perimeter

Answer 1

Answer:

Correct answer is 36 cm

Step-by-step explanation:

A=wl

P=2(l+w)

Solving forP

P=2l+2A

l=2·10+2·80

10=36cm

Answer 2

Answer:

36 cm²

Step-by-step explanation:

Area of the rectangle = L × B

= 10 × B = 80

= 80 ÷ 10 = B

B = 8

Perimeter of the rectangle = 2( L + B ) cm²

= 2( 10 + 8 ) cm²

= 2( 18 )cm²

= 36 cm²
