Question

Write the coordinates of the vertices of the geometrical figures and find its area.

Answer 1

solution:

1. co-ordinate of square

A(2,-1), B(7,-1), C(7,-4) and D(2,-4)

Area = length * Breadth

Length = 5 units

Breadth = 3 units

Area = 5*3 = 15 unit²

----------------------

Coordinate of second ||gm

S(2,-2), P(1,-4), O(4,-4) and R(6,-2)

Area og ||gm = Base * Altitude

Base = 4 units

Altitude = 2 units

∴Area = 4*2 = 8units²
