Question

What is the length of a rectangle whose area is 120 sq. cm and breadth is 10 cm?

Answer 1

Answer:

Area of rectangle =2( L + B )

120 =2(L+10)

120 =2L+20

120-20=2L

100=2L

100/2= L

L = 50

Answer 2

Area of rectangle = 120 cm²

Breadth = 10 cm

Area = L × B

120 = L × 10

120 / 10 = L

L = 12 cm

Length = 12 cm
