Area of a Triangle An isosceles triangle has equal sides 4 cm long and the included angle is θ. If θ increases at the
Answer:
that is the correct answer number 2 try that one
Perimeter = 2(L + W) = 20 or L + W = 10
And Area = L x W = 24
So with have the SUM "S" of 2 numbers and te PRODUCT "P' of same numbers, then
we can apply te quadratic equation X² -SX + P
X² - 10X + 24 = 0, solve this equation and you'll find L = 6 in and W = 4in
or 4 in x 6 in
