A triangular frame has an area of 36m^2, The height of the frame is 1m longer than the base. FInd the height and length of the base,

Question

I dont know how to solve it, if you can do it, please respond back with help... Thanks!

Answer 1

 

Area=1/2bh

 

Given area of 36m^2

 

1/2(x)(x-1)=36

Multiply both sides by 2 to remove deminator

 

(x)(x-1)=72

X^2-x=72

X^2-x-72=0 then factor

(x-9)(x+8)=0

X=9,-8 however since area must be positive, take the absolute value of 8

 

1/2(9m*8m)=36m^2
