Whats the area and perimeter 4yd 5yd 3yd

Area = ; Perimeter = 12 yd

Step-by-step explanation:

Given:

Sides given are 4yd, 5yd and 3 yd

let  a = 4yd b = 5yd and c = 3yd

We need to find Area and Perimeter.

Perimeter can be found by adding all sides

Perimeter= sum of all sides =

Area can be found using Hero's formula which states;

Area =

where

Substituting the values of s and sides we get area as;

Area=

Hence, Area = ; Perimeter = 12 yd

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
