Aloiza [94]

Answer:

Length = 13 cm

Step-by-step explanation:

Length (L) = 2 x Width (W) + 5

2 x (L + W) = 34

2 x (2W + 5 + W) = 34

6W + 10 = 34

6W = 34-10 = 24

W=4

Art [367]

Answer:The lateral area is $364\ cm^{2}$

Step-by-step explanation:

we know that

The lateral area of the right prism is equal to

$LA=Ph$

where

P is the perimeter of the base

H is the height of the prism

Find the perimeter of the base P

$P=4(7)=28\ cm$ ----> the rhombus has four equal sides

$h=13\ cm$

substitute

$LA=28(13)=364\ cm^{2}$
