Question

the length of a triangle is 3 times it's width. it the perimeter of rectangle is 96 metre, find the length and breadth of rectangle​

Answer 1

Answer:

$width = 12m \\ length \: =36 m$

Answer 2

Step-by-step explanation:

LET

the width of rectangle be X

the length of rectangle be 3X

so,

perimeter of rectangle=2(l+b)

$⟼2(3x + x) = 96 \\ \\ ⟼2(4x) = 96 \\ \\ ⟼8x = 96 \\ \\ ⟼x = 12$

hence:-

the width of rectangle=12m

the length of rectangle=3*12=36m
