P² = H² - B²
= 15² - 7²
= 225 - 49
= 176
P²= 176
P = √176
P = 13.26
So, L = 15 cm
B = 13.26
Perimeter = 2 x (L + B)
= 2 x ( 15 + 13.26 )
= 2 x 28.26
= 56.52 cm
= 15² - 7²
= 225 - 49
= 176
P²= 176
P = √176
P = 13.26
So, L = 15 cm
B = 13.26
Perimeter = 2 x (L + B)
= 2 x ( 15 + 13.26 )
= 2 x 28.26
= 56.52 cm
