Question

Can someone plz solve for A&B? Plz and if you do thank you so much :)

Answer 1

Part a-

area= 35

perimeter= 31

part b-

area= 25

perimeter= 18

Explanation:

to find the area of a triangle you multiply 1/2Bh

so for part A:

A=
`(1)/(2)` (10)(7) (honestly, you can just input the whole equation into the calculator)

A=(5)(7)

A= 35

and for part B:

A=
`(1)/(2)`(8.34)(6)

A= (4.17)(6)

A=25.02 (or just 25)

THEN, to find the perimeter you add up all of the sides

so for part A:

P= 14 + 10 + 7 = 31

and for part B:

P= 4
`(1)/(3)` + 8
`(1)/(3)` + 5
`(1)/(3)` = 17
`(3)/(3)` or 18

I hope this helps :)
