Answer:
48
Step-by-step explanation:
length 8cm
diagonal 10cm
then it's breadth = √(10^2 - 8^2) , (by Pythagoras theorem)
= √( 100- 64)
= √36= 6 cm
breadth 6cm
therefore,
area = length × breadth = 8×6 = 48 cm square

From right angled triangle ABC,we have
AB²+BC²=AC²
BC²=AC²-AB²
BC²=(10)²-(8)²
BC²=100-64
BC²=36
BC=√36
BC=6
therefore,area of rectangle=l×b
=8×6
=48
area of rectangle is 48cm²
