Question

Eind the perimeter of rectangle whose length is 35 cm and the abs diagonal is 37cm​

Answer 1

Answer:

Perimeter of rectangle is 94 cm.

Step-by-step explanation:

Given:

Length of rectangle (l) =35 cm.

Diagonal of rectangle (d) =37 cm.

Width of rectangle (b)=$\sqrt{d^{2} -l^{2} }$

                              =$\sqrt{37^{2} -35^{2} }$

                              =$\sqrt{1369-1225}$

                             =$\sqrt{144}$

                             =12 cm.

Perimeter of rectangle=2(l+ b)

                                    =2(35+12)

                                   =2×47

                                   =94 cm.
