Answer 1

The length of the missing side of the polygon with an area of 426 inches² is  31 inches.

Polygon

Polygon is a 2-dimensional shape. They are made of straight lines.

Therefore,

area of the polygon = 426 inches²

The composite figure can be divided into two rectangle. Therefore,

area = area of rectangle 1 + area of rectangle 2

area of rectangle = lw

where

• l = length

• w = width

Therefore,

let

the unknown side = x

426 = 26 × 11 + (26 - 19) (x - 11)

426 = 286 + 7x - 77

426 + 77 - 286 = 7x

7x = 217

x = 217 / 7

x = 31
