Step-by-step explanation:
all triangles are 180°
<h2>
x = 2 and y = - 3</h2>
Step-by-step explanation:
The given system of linear equations:
x - 2y = 8 ........ (1)
and 4x + y = 5 ........ (2)
To find, the values of x and y = ?
Multiplying equation (2) by 2, we get
2(4x + y) = 5 × 2
⇒ 8x + 2y = 10 ........ (3)
Adding equations (1) and (3), we get
x - 2y + (8x + 2y) = 8 + 10
⇒ x - 2y + 8x + 2y = 8 + 10
⇒ 9x = 18
⇒ x = 2
Put x = 2 in (1), we get
2 - 2y = 8
⇒ 2y =2 - 8
⇒ 2y = - 6
⇒ y = - 3
∴ x = 2 and y = - 3
Given => ABCD is a rectangle.
Where AB(length) = 12.5 units
AD(breadth) = 2.5 units
Area of rectangle = length × breadth
= 12.5 × 2.5
= 31.25 unit²
