Q.ue

Y = √(10² – 6²)

Y = √(10 – 6)(10 + 6)

Y = √(4)(16)

Y = √64

Y = 8

••

A = $sfintlimits^{5}_{2} (2x)dx \$

$sf = frac{2 {x}^{ 1 + 1} }{1 + 1} \$

$sf = frac{ {2x}^{2} }{2} \$

$sf = frac{ cancel2 {x}^{2} }{ cancel2} \$

$sf = {x}^{2} | _2 ^{5} \$

$sf = {5}^{2} - {2}^{2}$

$sf = (5 + 2)(5 - 2)$

$sf = (7)(3)$

$sf = 21$

••

Y × A

= 8 × 21
