plz mark as brain lst and like
we get, x = 1 and y = 5
Step-by-step explanation:
from first equation we get,
y = 4x +1
then,
putting the value of y in second equation :-
=》3x + 2y = 13
=》3x + 2 (4x + 1) = 13
=》3x + 8x + 2 = 13
=》11x = 13 - 2
=》11x = 11
=》 x = 11 / 11
=》 x = 1
putting the value of x in equation 1
=》y = 4x + 1
=》y = (4 × 1) + 1
=》y = 4 + 1
=》y = 5
The area here is 2 triangles and 3 rectangularso the total area is the sum of all areas area of triangle = 0.5 * base * height = 0.5 * 4 * 3 = 6 ft^2 the area of the rectangular 1 = 5 * 7 = 35 ft^2 the area of rectangular 2 = 4 * 7 = 28 ft^2 the area of rectangular 3 = 3 * 7 = 21 ft^2 so the total surface area = 2(6) + 35 + 28 + 21 = 96 ft^2
