Question

the measures of three sides of a triangle garden in the ratio 3:5:7 and the perimeter is 450 m then find the area of the garden

Answer 1

Let the sides are 3x,5x,7x
Perimeter =3x+5x+7x=450m
15x=450
X=30
a=90,150,210
Area = [s(s-a)(s-b)(s-b)]^1/2
Where s=(a+b+c)/2
S=450/2=225
Area =[225(15)(75)135]^1/2
=15*15*3*5*3^1/2=3375*3^1/2


Mark it as brieliance

Answer 2

Its as follows but please mark as brainliest.
3+5+7=15
Therfore their lenght is.
3/15 × 450 =90
5/15×450= 150
7/15× 450 = 210
Ok . Understood?

Hey can you tell what is the diagram as we dont know the base and height.
