One of the areas are 14 and 16 find the areas

The red triangle and the green rectangle are 14

The purple triangle and blue square are 16

Triangle is

(1/2)*Base*Height

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:

answer is because 4×10=40

and 98×4= is 392

40,392
