Question

the length of adjacent side of a rectangle are in the ratio 3:4. if the length of its diognal is 10 cm, find the length of side of the rectangle ​

Answer 1

Answer:

length =30

breath=40

Step-by-step explanation:

let the length be 3x

let the breath be 4x

by Pythagoras theorem

(3x)²+(4x)²=(10)²

9x²+16x²=100

25x²=100

x²=100

x=√100

x=10

then length is 3x

=3×10=30

then breadth is 4x

=4×10=40
