a rectangular room is twice as long as its breadth and its peimeter is 540 m. find the number of bricks of size 20 cm ×12cm to p

balu736 [363]

Answer:

Step-by-step explanation:

breadth = x

length = 2x

Perimeter = 540m

2*( length + breadth ) = 540

2 *(2x + x) = 540

3x = 540/2

3x = 270

x = 270/3

x = 90 m

Breadth = 90m = 90 *100 = 9000 cm

Length = 2*90 = 180 m = 180 * 100 = 18000 cm

No.of bricks = Area of room/ area of one brick

= 9000 * 18000 / 20 * 12

= 675000 bricks

$\frac{y\ miles}{x\ minutes}=\frac{4\ miles}{28\ minutes}\ \ |cross\ multiply\\\\28y=4x\ \ \ \ |divide\ both\ sides\ by\ 28\\\\\boxed{y=\frac{4}{28}x\Rightarrow y=\frac{1}{7}x}$
