The perimeter of a rectangular field is 240 m. If its length is 90 m, find (i) breadth (ii) area of the rectangle​

Sagot :

Answer :

Breadth = 30 m

area of the rectangle = 2700 m²

Explanation :

⋆Given :

↦Perimeter = 240 m

↦Length = 90 m

i) Breadth

Solution :-

Perimeter of a rectangle = 2 ( l + b )

240 = 2(90 + b)

240 = 180 + 2b

240 - 180 = 2b

[tex] \frac{60}{2} [/tex] = b

30m = b

(ii) Area of a rectangle

Solution :-

Area of a rectangle = l × b

Area of a rectangle = 90 m × 30 m

Area of a rectangle = 2700 m²
