Answer 1

Look at the picture.

$A=\dfrac{1}{2}(8+6)\cdot4=\dfrac{1}{2}(14)\cdot4=7\cdot4=28$

Answer 2

Answer:

Perimeter =     14 + 2sqrt(17)

Area =28

Step-by-step explanation:

FG = 8  counted

EH = 6  counted

using the pythagorean theorem

height = 4 and the base = 1 in the right triangle

HG^2 = 4^2 + 1 ^2

hg^2 = 16+1

hg^2= 17

hg= sqrt(17)

ef^2 = 4^2 + 1 ^2

ef^2 = 16+1

ef^2= 17

ef=sqrt(17)

Perimeter = EF+FG + GH+HE

                   sqrt(17)+ 8+ sqrt(17) + 6

                     14 + 2sqrt(17)

A =1/2 (b1+b2) * h  

b1 =EH  b2 = FG and h = 4 height that we used in the perimeter

= 1/2 (6+8) * 4

= 1/2 * 14*4

=28
