Question

the area of a rectangular sheet is 300 cm² the length of sheet is 15 cm find the perimeter of the rectangular sheet​

Answer 1

Step-by-step explanation:

area of rectangle = 300 cm²

or, l * b = 300

or, 15 * b = 300

or, b = 300/15

or, b = 20 cm

therfore, lenght = 15 cm²

breadth = 20 cm²

perimeter of rectangle is 2(l+b)

= 2(15+20) = 2 * 35

= 70 cm. ans
