Question

ABCD is a rectangle,BC=24cm,AC=25cm.Find BD and AB

Answer 1

if u know the rectangle formulae u can find easily

Answer 2

In△ABC,∠C=900△ABC,∠C=900

Therefore, by PYTHAGORAS’ Theorem- AB2=BC2+AC2AB2=BC2+AC2

Here, AC=5cmAC=5cmandBC=12cmBC=12cm

=> AB2=52+122=25+144=169=132AB2=52+122=25+144=169=132

Therefore, AB=13cmAB=13cm
