Answer:
Explanation:
Do you know the formula for area of a triangle?
A = (1/2)bh
"Area is half of the base times the height."
They give us 2 of those values, so we can solve for the third one. It's base, b, we're looking for:
(1/2)bh = A
Let's get rid of that half by multiplying both sides by 2:
bh = 2A
Now let's get b by itself by dividing by h:
b = 2A/h
Now just plug in the area and the height they gave us:
b = 2(150 cm²)/6 cm
b = 300cm/6 (Notice how one of the cm's cancelled out.)
b = 50 cm
Check it by using b and h to find the area:
A = 1/2(50)(6) = 1/2(300) = 150
And that's the area they gave us, so our answer checks out.
