Question

calculate the area: triangle with base 11mm, height 4mm, and one side 7mm #1 40 m² #11 #2 32 in² #12 #3 45 in² #13 #4 20 mm² #14 #5 56 cm² #15 #6 48 in² #16 #7 84 in² #17 #8 #18 #9 #19 #10 #20

Explanation:

Step1: Recall triangle area formula

The area of a triangle is $\frac{1}{2} \times \text{base} \times \text{height}$

Step2: Substitute given values

Base $= 11\ \text{mm}$, Height $= 4\ \text{mm}$
$\text{Area} = \frac{1}{2} \times 11 \times 4$

Step3: Calculate the result

$\text{Area} = \frac{1}{2} \times 44 = 22$

Answer:

$22\ \text{mm}^2$
