Question

the area of rectangle piece of cardboard is 80 sq cm find its length if its breadth is 6 1/4 cm

Answer 1

Hello friend

Area of a rectangular cardboard is 80cm²

Breadth is 6 1/4=25/4 cm

Area of a rectangle is given by length*breadth

Area=l*b

80=l*25/4

80*4/25=l

length = 320/25=64/5 or 12 4/5 cm

Hope it helps!!

Answer 2

Area of the rectangle = length × breadth

Breadth = 6 1/4 = 25/4 cm

length × breadth = 80 cm²

length × 25/4 = 80 cm²

length = 80÷25/4

length = 80×4/25

→ length = 64/5 cm

→ length = 12 4/5 cm

Hope it helps
