2. The formula for the area of a triangle is A= b. If the base (b) = 10 cm and the height (h) = 6 cm, what is
the area of the triangle?
3. The length (I) of the rectangle is x2 + 2x - 3 and the width (w) is 5x + 4, what is the perimeter of the
rectangle?
4. From the sum of 3x3 + 7x2 - 5 and 2x2 + 3x + 8 take away 5x2 + x-5.
5. What should be added to 3x3 + 4x2 -7 to have a sum of 4x3 + x2 + 5.

Answer:

(2)solution:

A=(b×h)

A=(10cm+6cm)

A=16cm

(3)solution:

P=2(l+w)

P=2(ײ+2×-3 + 5×+4)

P=2(ײ+7×+1)

P=2ײ+14×+2

(4)solution:

3׳+7ײ-5 + 2ײ+3×+8

=3׳+9ײ+3

3׳+9ײ+3 + 5ײ+×-5

=3׳+14ײ+x-2

(5)solution:

3׳+4ײ-7 - (-×)+4ײ+12

=4׳+ײ+5
