I need help on this! please help will mark brainliest:)
bazaltina [42]

Answer:

P = 48 feet

A = 84 square feet

Step-by-step explanation:

use the Pythagorean Theorem 2 times to find the bases of the two triangles created by the height of eight

1st Δ :  one leg is 8 and the hypotenuse is 10

          a² + 8² = 10²

          a² + 64 = 100

           a² = 36

            a = 6

2nd Δ :  one leg is 8 and the hypotenuse is 17

          b² + 8² = 17²

          b² + 64 = 289

           b² = 225

           b = 15

Perimeter = 10 + 17 + 6 + 15 = 48 ft

Area = 1/2(8)(6 + 15)  = 4(21) = 84 sq ft

This shape is made of three identical semicircles.
Yuliya22 [10]

Answer:

48cm

Step-by-step explanation:

The perimeter of first shape is 36cm. There are 3 semi circle (curves).

Therefore,

3 curves of semicircle (arc length) = 36

1 curve of semicircle (arc length) = 36/3

= 12cm

In picture 2,

4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)

So,

4×12 = 48cm
