120 cm will be the area

Hope it helps you✨

Answer 2

Answer:

AREA=120cm²,PERIMETER=46cm

Step-by-step explanation:

Length =15 cm, Diagonal=17cm

IF WE DRAW A ROUGH SKETCH OF THE GIVEN QUESTION WE'LL SEE THAT THE DIAGONAL DIVIDES THE RECTANGLE INTO TWO EQUAL RIGHT ANGLED TRIANGLE.

THUS WE CAN USE THE PYTHAGORAS THEOREM TO FIND THE THIRD SIDE OR BREADTH.

L²+B²=D²

15²+B²=17²

B²=289-225

B² =64

B=√64

B=8cm

HENCE ,

AREA = L*B

          = 15*8

          =120cm²

PERIMETER=2(L+B)

                   =2(15+8)

                   =2*23

                   =46cm
