Question

lenth of a triangle is thrice that of it's breath perimeter of rectangle is 80 metre find the lenth and breath of rectangle​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of rectangle is 80 metres

Length of a rectangle is thrice that of its breadth.

Let the breadth be x

Therefore, length =3x

ATQ.

2(3x+x)=80

6x+2x=80

8x =80

X=80/8=10

Therefore breadth =10 metre

And length =3x=3x10=30 metre

Explanation:

Answer 2

Answer:

let  the breadth be x

[3x+x ] x 2=80m

4x x 2=80

4x= 80/2

4x=40m

x=40/4

x=10

therefore the length is 30m and breadth is 10m
