Answer:

76 cm

Step-by-step explanation:

To find perimeter, you find the total of the sides.

A rectangle has 4 sides, and 2 equal sides.

So, add 14+14 which is 28.

Then add 24+24 which is 48.

Now add 48 and 28.

48+28=76

<u>Final answer</u>

76 cm

Answer:

4.6.

Step-by-step explanation:

The rocket hits the ground when h(t) = 0. So

-16t^{2} + 72t + 7 = 0

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

In this question:

-16t^{2} + 72t + 7 = 0

So

a = -16, b = 72, c = 7

Then

\bigtriangleup = 72^{2} - 4*(-16)*7 = 5632

t_{1} = \frac{-72 + \sqrt{5632}}{2*(-16)} = -0.1

t_{2} = \frac{-72 - \sqrt{5632}}{2*(-16)} = 4.6

Time is a positive measure, so the answer is 4.6.

Find the area of each triangle then and them together, so:

1/2(15×8) =60

plus

1/2(15×8) =60

plus

1/2(23×8)=92

plus

1/2(23×8)=92

60+60+92+92=304

304 is the total area.
