Question

If the perimeter of a room is 900 m. Its length is160 m. Find its breadth and area​

Answer 1

Answer:

answer :

given:

• perimeter = 900 m
• length = 160m

to find :

• breadth and area

solution :

➜let breadth be x

➜then perimeter = 2(l+b)

→ 900 = 2( 160 + x )

→ 900 = 320 + 2x

→ 900 - 320 = 2x

→ 2x = 580

→ x = 290

breadth = 290 cm

now area = l × b

→ 160 × 290

→ 46400 cm²

therefore ,

• breadth = 290 cm
• area = 46400 cm²
