Question

15. The area of a rectangular field is 456m2 and its length is 24m find the breadth and
perimeter of the field.
​

Answer 1

we know that the formula for calculating area is= length× breadth

LENGTH- 24 AREA- 456

LET BREADTH BE = x metres

therefore, BREADTH= 456/24= 19m

Answer 2

Given

• Area of Rectangular Field ⇒ 456 m²
• Length ⇒ 24 m

____________________________________

To Find

• The Breadth
• Perimeter of Field

____________________________________

Solution

Area of Rectangular Field ⇒ 456 m²

Area of Rectangle ⇒ Length × Breadth

Length ⇒ 24 m

Breadth ⇒ x m

Breadth ⇒ Area of Rectangle ÷ Length

Breadth ⇒ 456 ÷ 24

Breadth ⇒ 19 m

∴ The breadth of the rectangular field is 11 m

Perimeter of Rectangle ⇒ 2 (Length + Breadth)

Perimeter of Rectangular Field ⇒ 2 (11 + 24)

Perimeter of Rectangular Field ⇒ 2 (35)

Perimeter of Rectangular Field ⇒ 70 m

∴ The perimeter of the rectangular field is 70 m
