Question

The
area of a rectangle with breadth 5 cm is 30 sq. cm. Find its length and perimeter.​

Answer 1

Answer:

Area of rectangle = l × b

breadth = 5cm

let the length be x

then,

30 cm² = x × 5 cm

30 cm² ÷ 5 cm = x

6cm = x

■ length = 6cm

perimeter = 2(l + b)

2×( 6 +5)

2×11

■ 22 cm

Answer 2

Step-by-step explanation:

Area of rectangle = L×B

30 sq.cm. = L × 5

30 ÷ 5 = L (6cm = L)

Perimeter of rectangle

= 2×(L+B)

=2×( 6+5)

=2×(11)

[22 cm
