( i). base=15cm , altitude=8cm

please friends tell me this correcty

please

​

Answer 1

60cm² is the area

Step-by-step explanation:

area=1/2×base×height

area(a)=b×h

a=1/2×15×8

a=120×1/2

a=60

Answer 2

Answer:

• Area of the triangle is 60cm² ✔

Step-by-step explanation:

Given dimensions of the triangle :

• base = 15cm.
• altitude = 8cm.

Here, base and altitude of the △is given, we need to find it's area.

Area of a △ is given by :

→ ½ · base · height

• height is the altitude of the△.
• Units, are in centimeter.

From the given dimensions :

→ Area of the △: ½ · 15 · 8

→ 15 · 4

→ 60cm²

∴ Area of the triangle is 60cm²
