Area of shaded region = 34 cm²

$\textsf{ \underline{\underline{Steps to solve the problem} }:}$

Area of shaded region = Area of bigger rectangle - Area of smaller rectangle.

Area (big) :

$\qquad❖ \: \sf \:13 \times 6$

$\qquad❖ \: \sf \:78 \: \:c m {}^{2}$

Area (small) :

$\qquad❖ \: \sf \:11 \times 4$

$\qquad❖ \: \sf \:44 \: \: cm {}^{2}$

Area of shaded region :

$\qquad❖ \: \sf \:78 - 44$

$\qquad❖ \: \sf \:34 \: \: cm {}^{2}$

$\qquad \large \sf {Conclusion} :$

Area of shaded region = 34 cm²

Solve i + j + t (3i - j) = -i + s (j)<br> In the context of Vector Equations of a Line

Oksana_A [137]

Answer:

r = i + j + (-2/3)(3i - j)

Step-by-step explanation:

Vector Equation of a line - r = a + kb ; where r is the resultant vector of adding vector a and vector b and k is a constant

if a = i + j ; b = t(3i - j) and r = -i +s(j)

for this to be true all the vector components must be equal

summing i 's

i + 3ti = -i; then t = -2/3

j - tj = sj; then s = 1-t; substitue t; s=1+2/3 = 5/3

so r = i + j + (-2/3)(3i - j) which will symplify to -i + 5/3j
