Answer 1

Step-by-step explanation:

= 2160 area of ABCED Of the figure

Answer 2

Answer:

Area of the figure is 12cm²

Step-by-step explanation:

We need to find the area of ABCED

Here, This figure can be splitted into two shapes :

• Rectangle.
• Triangle.

First

Finding the area of the rectangle i.e., l × b

Where,

l (length) = 6cm

b (breadth) = 5cm

So,

Area of the rectangle ABCD = 6 × 5 = 30cm²

Second,

We are going to find the area of the ∆ CED

Where,

There's sides are 3cm, 4cm, and 5cm

• We need to find the semi perimeter before using the heron's formula to find the area.

So,

We know that,

Semi perimeter = a + b + c/2 (a, b, c denotes the sides)

= Semi perimeter = 3 + 4 + 5/2

= 12/2

= 6cm

Using the heron's formula :

= √s(s - a)(s - b)(s - c)

= √6(6 - 5)(6 - 4)(6 - 3)

= √6(1)(2)(3)

= √36

= 6cm²

Hence,

Total area of the figure :

➡ Area of rectangle ABCD + Area of ∆ CED

️➡ (6 + 6)cm²

️➡️ 12cm² ans.
