1.	11. Area of a rhombus is 90 cm2. If the length of one diagonal is 10 cm then what is length of second diagonal
Answer» en Area of rhombus is 90cm² Length of one DIAGONAL is 10cm To Find we have to find the length of second diagonal $\sf\huge\bold{\underline{\underline{{Solution}}}}$ Since,Area is GIVEN so,we will apply the formula for area of rhombus and assume some Variable in place of Diagonal 2 we have to find . Area of Rhombus= D1 × D2 ÷ 2 ↣Area of Rhombus= 10× Diagonal 2 ÷ 2 let length of other diagonal be 'x' ↣90= 10 × x ÷2 ↣90= 10x/2 ↣10x= 90×2 ↣10x=180 ↣x=180/10=18 ↣x= 18 hence,length of other diagonal is 18cm Check: Area of Rhombus= 18×10÷2 Area of Rhombus= 180÷2=90cm² Extra information=> Area is Space or region which is covered by a solid object/figure it is said to be area of that object. Area depends upon the dimensions of the figure.If dimensions is larger then larger will be the area of that object/figure and vice -versa. Properties of Rhombus: All sides of rhombus are equal and opposite sides are parallel. Diagonals of Rhombus bisects each other at 90°. There are four congruent right angled TRIANGLES formed between the TWO diagonals

11. Area of a rhombus is 90 cm2. If the length of one diagonal is 10 cm then what is length of second diagonal

Answer»

Area of rhombus is 90cm²

Length of one DIAGONAL is 10cm

we have to find the length of second diagonal

$\sf\huge\bold{\underline{\underline{{Solution}}}}$

Since,Area is GIVEN so,we will apply the formula for area of rhombus and assume some Variable in place of Diagonal 2 we have to find .

↣Area of Rhombus= 10× Diagonal 2 ÷ 2

let length of other diagonal be 'x'

↣90= 10 × x ÷2

↣90= 10x/2

↣10x= 90×2

↣10x=180

↣x=180/10=18

↣x= 18

hence,length of other diagonal is 18cm

Area of Rhombus= 18×10÷2

Area of Rhombus= 180÷2=90cm²

Area is Space or region which is covered by a solid object/figure it is said to be area of that object.

Area depends upon the dimensions of the figure.If dimensions is larger then larger will be the area of that object/figure and vice -versa.

All sides of rhombus are equal and opposite sides are parallel.
Diagonals of Rhombus bisects each other at 90°.
There are four congruent right angled TRIANGLES formed between the TWO diagonals
