Answer 1

h=15,7 ft

l1=19.8

l2=l1=19.8

Explanation:

A=(b×h)/2

110=x×14/2

x×14=220

x=220/14=15,7

h=15.7 ft

l=rad(144+246.7)=19,8

l1=l2=19,8

Answer 2

Explanation:

Area = 1/2*b*h

110 = 1/2 * 14 * h

15.714 = h

Pythagoren th

c^2 = a^2 + b^2

c^2 = 7^2 + (15.714)^2

c^2 = 49 + 246.93

c^2 = 295.93

c = 17.2
