Question

A triangle ABC has a base of (x+3)cm and height of x cm .if its area is 5 cm². Calculate the length

Answer 1

Answer:

hey here is ur answer

pls mark it as brainliest

Explanation:

so now here using area of triangle formula

we get

area of triangle=12×base×height

therefore 5=1/2×(x+3).x

ie 10=x square+3x

so x square+3x-10=0

ie x square+5x-2x-10=0

ie x(x+5)-2(x+5)=0

ie (x+5)(x-2)=0

so x=-5 or x=2

now since dimension length of any geometric figure is never negative

x=-5 is absurd

thus x=2

substitute value of x in missing terms

you get base=5 cm and height=2 cm
