Ashley can help his father and it is a very easy that she can solve for the triangular portion of the roof by using the formula of the area of a triangle which is equivalent to A=1/2*H*B. Ashley needs to measure the length of both base and height of the triangular portion of the roof. Then, she can proceed with the equation.
Hey there!
Let’s turn everything into yards (instead of feet) so we can determine which is greater
To do this, all we have to do is divide 3 (that’s how many feet are in a yard) by 429 & 460 (these are the 2 lengths that are represented by feet)
429 ÷ 3 = 143
460 ÷ 3 = 153.333... (let’s round to 153)
Now, we determine which is greater:
150 yards > 143 yards
So, 150 yards is greater than 143 yards (or 429 feet)
130 yards < 153 yards
So, 130 yards is less than 153 yards (or 460 feet)
Hope this helps you!
God bless ❤️
