Answer: 14 cm^2
Explanation:
The area of a triangle is (Length*Width)/2 this is because a triangle is half of a square (which is Length*Width).
If the area is 63 and the length is 9 then to find the area we need to reorganize the previous equation of A=(L*W)/2.
We need to figure out the length from:
Area (A) which is 63
And Width (W) which is 9
If we plug it into our equation we get: 63=(L*9)/2
Using algebra we can multiply both sides by 2 and get 63*2=(L*9) which in turn gives us 126=L*9.
If we divide both sides by 9 we get 126/9=L which becomes 14=L. The final answer is 14.
