Answer 2

Answer: a. area= 35ft²   &   perimeter= 31ft

              b. area= 25in²   &  perimeter= 18in

Step-by-step explanation:

a. area= 1/2 x base x height           Perimeter= 14+7+10

           = 1/2 x 10 x 7                                        = 31ft

           = 35ft²                

b. area= 1/2 x base x height           Perimeter= 25/3 + 13/3 + 16/3

           = 1/2 x 25/3 x 6                                    = 18in

           = 25in²
