Question

the ratio of length and wealth of a tower is 5 ratio 3 and its perimeter is 48 find the measurement of door​

Answer 1

Given:

Ratio = 5:3

Length = 5x

Breadth = 3x

Solution :

Perimeter of rectangle = 2 (length + breadth)

48 = 2( 5x + 3x)

48 = 2(8x)

$\frac{48}{2} = 8x$

$x \: = \frac{48}{2 \times 8}$

$x = \frac{48}{16}$

$x = 3$

Length = 5 x 3 = 15

Length = 5 x 3 = 15Breadth = 3 x 3 = 9

Answer 2

Correct Question:-

• The ratio of length and wealth of a door is 5:3 and its perimeter is 48m find the measurement of door.

⠀

Given:-

• Ratio of length and wealth of a tower is 5:3.
• Its perimeter is 48m.

⠀

To find:-

• Measurement of door.

⠀

Solution:-

Let,

• the length of the door be 5x.
• breadth of the door be 3x.

⠀

☆Perimeter of rectangle = 2(l + b)

⇛ 48 = 2(5x + 3x)

⇛ 48 = 2(8x)

⇛ 48/2 = 8x

⇛ 24 = 8x

⇛ x = 24/8

⇛ x = 3

⠀

Therefore,

• Length = 5x = 5 × 3 = 15 m
• Breadth = 3x = 3 × 3 = 9 m

⠀

Hence,

• the Length of the door is 15 m and breadth of the door is 9 m.
