find the perimeter and the area of a rectangle

Question

Length of the triangle= 4+2w

width of the triangle= 6

Answer 1

P = 2L + 2W

 

P = 2(4 + 2W) + 2(6)

 

P = 8 + 4W + 12

 

P = 20 + 4W

 

W = 6

 

P = 20 + 4(6) = 20 + 24 = 44

 

A = L * W

 

A = (4 + 2W)(6)

 

A = (4 + 2 * 6)(6)

 

A = (4 + 12)(6)

 

A = 16 * 6 = 96 square units
