Answer 1

Answer:

Given breadth of the rectangle = 90cm

Given perimeter of the rectangle = 390cm

Length of the rectangle = ?

We know that perimeter of rectangle is 2(l + b). So, by substituting the values, we will the measure of the length.

⇒ Perimeter of the rectangle = 2(l + b)

⇒ 390cm = 2(l + 90)

⇒ 390cm/2 = l + 90

⇒ 195 = l + 90

⇒ 195 - 90 = l

⇒ 105cm = l

∴ Length of the rectangle = 105cm

And now, the area of the rectangle = length * breadth

⇒ 105cm * 90cm

⇒ 9450cm²

∴ Length of the rectangle = 105cm

∴ Area of the rectangle = 9450cm²

Thnx and have a nice day!
