Question

the area of a rhombus 85
metre square if its perimeter be34m find it attitude​

Answer 1

Given:area of rhombus=28cm

perimeter of rhombus=28cm

all four sides of rhombus are equal

then,28/4=7cm

length of 1 side=7cm

area of rhombus=base×height (altitude = height)

7×height=28

height=28/7

=4cm

Hope this helps.

Mark as brainliest if it does.

You are welcome!!

Answer 2

Given

Area of Rhombus=85 m²

Perimeter=34 cm

$area = \frac{1}{2} \times base \times altitude$

We Know That In Rhombus Length of All Sides are Equal.

There Are Total 4 sides Of Rhombus.

Length of 1 side=34/4=17/2 m

Base=17/2 m

Altitude=?

Area=85m²

$\frac{1}{2} \times b \times a = 85 \\ \\ \frac{1}{2} \times \frac{17}{2} \times a = 85 \\ \\ a = 85 \times \frac{2}{17} \times 2 \\ \\ a = 5 \times 2 \times 2 \\ \\ a = 20$

Altitude=20m
