Sa of rhombus is 1/2× D1×D2. 96=1/2×16×D2 96×2÷16=D2 D2=16. As we know that diagonals of rhombus bisect each other at right angles. Therefore; By Pythagoras theorem; S1(square)=64+64 S1(Square )=128(root) =11. 3. Similarly each side is 11. 3cm

If other diagonal is 12 cm.. Diagonals in rhombus bisects at 90°. It forms a right angled triangle... Length of diagonals after bisecting the diagonals=8,6 by diving them in 2 parts... Now, pythagorous theorum, H²=P²+B² H²=8²+6² H²=64+36 H²= 100 H=√100 H= 10 CM SIDE : 10 CM HOPE U UNDERSTAND

Simran Kaur 6 years, 3 months ago

Area of rhombus =1/2 (product of diagonals) 96=1/2*16*x 96=8*x x=96/8 x=12 Length of other diagonal is 12 cm.

Sia ? 6 years, 3 months ago

Given: In {tex}\triangle{/tex}ABC, BC = 7 cm, {tex}\angle{/tex}B = 75^o and AB + AC = 13 cm.
Required: To construct the triangle ABC.
Steps of construction :

Draw the base BC = 7 cm.
At the point B construct an angle YBC = 75^o.
Cut an arc from B as centre and radius equal to AB + AC = 13 cm. on the ray BY. Name it D.
Join DC.
Draw the perpendicular bisector of line segment DC which intersects BD at some point name it A.
Join AC.
ABC is the required triangle.
