3- A rectangle has an area of 30 square meters arm a perimeter of 34 meters the dimensions , of the rectangle I 9 , a J v ft HA
Leto [7]
If you are looking for the answer to the question above you have to ask yourself what two numbers multiply to 30 and equal 17 when added up. We halve the perimeter to make this easier. So your answer is 15 and 2 because 15 *2=30. If the sides are 15 and 2 then, 15(2) +2(2)=34. There is your answer.

Use a net to find the surface Area of the square pyramid The height of the pyramid is 9 yes and the base sides are all 2.5 yrds
Cerrena [4.2K]

Answer:

Area = 51.68yd^2

Step-by-step explanation:

Given

h = 9yd -- height

a = 2.5yd --- base sides

Required

Determine the surface area

The net is not given. So, I will solve directly.

The surface area is calculated as:

Area = a^2 + 2a\sqrt{\frac{a^2}{4} + h^2}

So, we have:

Area = 2.5^2 + 2*2.5\sqrt{\frac{2.5^2}{4} + 9^2}

Area = 6.25 + 5\sqrt{\frac{6.25}{4} + 81}

Area = 6.25 + 5\sqrt{1.5625 + 81}

Area = 6.25 + 5\sqrt{82.5625}

Area = 6.25 + 5* 9.086

Area = 51.68yd^2
