If a certain cannon is fired from a height of 9.1 meters above the​ ground, at a certain​ angle, the height of the cannonball above the​ ground, h, in​ meters, at​ time, t, in​ seconds, is found by the function h(t)=−4.9t2+24.5t+9.1. Find the time it takes for the cannonball to strike the ground.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width
