A) 110 B) 120 C) 130 D) 140

Answer 1

Answer:

hello dear,

Step-by-step explanation:

Let the rectangle be ABCD

Let BC = 15m

diagonal ,AC = 17 m

By applying pythagorus theorem,

AC² = AB² + BC²

⇒ AB = √AC²-BC²

⇒ AB = √17²-15²

⇒AB = 8m

Area of rectangle = l*b

                           = 15*8 = 120 m²

i hope it helps u
