The diagram shows isosceles triangle ABC. AB= AC=7.5. The height of the triangle is 6cm. Calculate the area of the triangle

22.5 cm

Step-by-step explanation:

Triangle area is (L x W) / 2

7.5 x 6 = 45

45 / 2 = 22.5

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
