0.04 inches²

Step-by-step explanation:A of Triangle = 1/2*B*H where B is base and H is height. Find the area of the bigger triangle and then subtract the area of the smaller triangle

1/2*(0.4)*(0.3) = 0.06

1/2*(0.4)*(0.1) = 0.02

0.06 - 0.02 = 0.04

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:
