Question

а The perimeter of a square is 48 m. Its area is (1) 121 sqm (2) 148 sq m (3) 144 sqm (4) 192 sqm The ratio of length and breadth of a rectangle is 5: 4. If the length is 25 m, the breadth is (2) 20 m (3) 10 m (4) 12 m hoight is 2 m. What will be the area of the wal 11) 15 m​

Answer 1

Step-by-step explanation:

Perimeter of the square =4× side =48 m

Length of side of the square =48/4 =12m

Now, area of this square =side× side

=144 sq m

Given, the area of a rectangle is 4 sq m less than the area of given square.

Area of rectangle =144−4=140 sq m

⇒ Length × Breadth =140 sq m

⇒14 m× Breadth =140 sq. m

⇒ Breadth =10 m

Answer 2

Answer:

144 sq m
