Question

find the breadth and perimeter of the rectangle, area-90sqcm'. length =15 cm​

Answer 1

Answer:

6 cm of Breadth Value

Perimeter 42cm

Step-by-step explanation:

Let B Be Breadth Of Rectangle

15 × B = 90sqcm

B = 90/15

B=6 cm

Perimeter:

15 × 2 + 6 × 2 = 30 + 12 = 42cm

Answer 2

Answer:

area of rectangle = length × breadth

90 cm² = 15 cm × breadth

breadth = 90 cm² ÷ 15 cm

Breadth = 6 cm

Perimeter = 2( length + breadth )

= 2( 15 + 6 )

= 2 × 21

= 42 cm

Perimeter = 42cm
