Question

If the area of a triangle DEF above is equal to the area of square M (not shown), what is the length of a side of the square?

Answer 1

where is the triangle?

Answer 2

its not possible to evaluate the area of that triangle as we need its height as well as its base

Answer 3

the height is 10 sorry forgot to put it

Answer 4

Ok area of triangle = (1/2) * base 8 height = 1/2 * 5 * 10

can you work that out?

Answer 5

yes 25

Answer 6

* 1/2 * base * height

Answer 7

ok so if the length of the side of the square is x then its area is x^2

so x^2 = 25


what is x?
