if the coordinates of quadrilateral ABCD are (-3,5) , (3,5) , (3, -5) and (-3,-5), then the area of quadrilateral ABCD is equal to brainly
Answers
Step-by-step explanation:
The given figure is a rectangle because it's opposite sides are equal
Area of rectangle= Length× Breadth
Length=10cm
Breadth=6cm
6×10=60
Area of given quadrilateral is 60 square cm
Given : coordinates of quadrilateral ABCD are (-3,5) , (3,5) , (3, -5) and (-3,-5)
To Find : area of quadrilateral ABCD
Solution:
A (-3,5) , B (3,5) , C (3, -5) and D (-3,-5)
AB = (3 - (-3)) = 6
BC = (5 - (-5)) = 10
CD = 6
AD = 10
AC = BD = √6² + 10²
Opposite sides are equal Diagonals are equal
Hence Quadrilateral ABCD is a rectangle
Area of rectangle = length * Breadth
=> Area of rectangle = AB * BC
= 6 * 10
= 60 sq units
