Question

the area of a triangle is equal to the area of a square of side 40m.calculate the base of the triangle if its altitude is 80m

Answer 1

Answer:

40 m

Step-by-step explanation:

area of square formula =

=side * side

=40 m * 40 m

=1600 m^2

area of triangle formula =

=1/2 * base * height = 1600 m^2

=1/2 * x * 80 m = 1600 m^2

=1 * x * 80 m = 1600 * 2

=1 * x * 80 m = 3200

=x * 80 m = 3200

=x = 3200/80

=x = 40 m

THEREFORE THE BASE OF THE TRIANGLE IS 40 m.

Answer 2

Answer:

40m

Step-by-step explanation:

Sometimes equations like these may be tricky, so what you can do is work backwards. Based on the question, you were given the height and you can find the area of the triangle.

area of a square is side*side or side²

hence, 40*40 or 40²= 1600

but they want the base of the triangle

we know area of a triangle is (base ×height)÷2 or 1/2 (base×height)

if you multiply the area ×2

=1600×2

= 3200

then, divide the 3200 by 80

=3200÷80

=40

and that's just a trick of how to work backwards given what you already have.
